Jeremy uses the linear function G=12h+50 to represent the grade, G (in points out of 100), that he can earn on an exam as a function of h, the number of hours he spends studying for the exam.
1.) Identify the slope and y-intercept of Jeremy's function and explain what they mean in context of the problem.
2.) If Jeremy spends 3 hours studying for the exam, what grade does he expect to earn?
3.) How many hours should Jeremy study if he wants to earn a perfect score on the exam?
